I have a 2-post and as Zep says, you can do most things on them. Whatever you do though , don't compromise your wellbeing by buying Chinese, many are disguised to look German, even having German importers, claiming to have the factories there so dig carefully.
If you want to scare yourself, take a look at the HSE website regarding post lifts and other garage equipment.
Phil (in France) did a lot of looking before settling on his ones, included in his purchase were huge spreader plates for the 2-post even though he knew the floor was good under them!
I made the choice to go for one after the 4200 fell off an axle stand and pinned me against a cabinet in the garage one afternoon. Nobody about to help, fortunately I was not hurt and able to wiggle like a fish and get myself free! Never again...
Mine is a Naussbaum, genuinely German but was second hand, 3-phase and took a lot of work to get working. With hindsight I'd have bought new, OK the price of a small hatchback but what value life?
